For a long time I simply accepted, that there is no easy way to connect an Android phone ,that no longer has mass storage support. Until the Update of GVFS.

Connecting seems to work out of the box now. I can see most files (no hidden ones) and I can move and write. However, as soon as I try to use an application like Banshee or Clementine, weird things start to happen. I get error messages like this. Always after closing this message a similar one appears with the last number being "27". After that message I can no longer access the phone in nautilus. Only reconnecting and closing any applications able to interfere with devices seems to resolve the problem so far.

To be fair... I don't even know if this is the fault of GVFS. When I got my phone half a year ago I tried many things to get it connect and I don't remember all of it. I wrote some auto mount scripts specifically for this phone, but I don't know how to erase them :/

Thank you for your help!
